Jelle's Marble Runs

Jelle's Marble Runs is a YouTube channel based in the Netherlands centered on marbles, marble runs and marble races. It is run by the brothers Jelle and Dion Bakker. The channel spoofs the Olympic Games, Formula One, and other sporting events with marbles and treats the cast of marbles as though they were athletes.

The Marble League (formerly MarbleLympics and previously Marble Olympics) has a choreographed Opening and Closing Ceremony, often created using stop motion. Many of the sports are designed to resemble Olympic sports. Each year, the channel uploads a new series of the Marble League featuring different events and teams, which are introduced in the Qualifying round. If a team does not qualify, they are sent to the Showdown, essentially a shorter Marble League; any team finishing in the bottom four in the Showdown will not compete in the Qualifying round the next year.

The channel also uploads Marbula One, a marble version of Formula One where many of the same teams from the Marble League send duos to faceoff, if certain marbles or teams do too badly in the season they don't appear in the next season and they get replaced by different marbles or teams. There is also the Sand Marble Rally, which also features a Qualifying round and instead of teams there are individual marbles, which are different from those in the Marble League, Marbula One and many other different marble races and events. As of July 4, 2025, the current channel has over 1.44 million subscribers with more than 196 million views.
